PORTABLE RACK.

SPECIFICATION forming part of Letters Patent No. 795,111, dated July 18,1905.

Application filed March 31, 1905- Serial No. 253,102.

To a, whom it may concern:

Be it known that I, LESLIE A. FRIEND, of Melrose, in the county ofMiddleseX and State of Massachusetts, have invented certain new anduseful Improvements in Portable Racks, of which the following is aspecification.

This invention relates to a portable rack comprising a frame havingwheels or casters and adapted to be convenientlymoved about and trays orshelves slidinglyengaged with the frame and adapted to be projectedtherefrom to permit the reception and removal of articles intended to besupported by the trays.

The invention has for its object to provide a rack of this characteradapted particularly for holding pies; and it consists in theimprovements hereinafter described and claimed, resulting in theproduction of a rack having a series of trays adapted to be projectedfrom either side of the portable frame, the arrangement being such as toprevent the center of gravity of the rack from being moved outside thecenter of the base of the frame by the simultaneous projection of allthe trays in either direction, and, further, such that the simultaneousprojection of one tray in one direction and an adjacent tray in theopposite direction will cause the uncovering of the lower tray andpermit it to be conveniently loaded and unloaded.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of a rack embodying my invention.Fig. 2 represents a section on line 2 2 of Fig. 1, the projected trayshown at the right in Fig. 1 being omitted. Fig. 3 represents a sectionon line 3 3 of Fig. 1. Fig. 4 represents a section on line 4 1 of Fig.2.

The same reference characters indicate the same parts in all thefigures.

In carrying out my invention I constructa rectangular frame having fourvertical corner-posts a and suitable horizontal cross-bars a rigidlyconnected with the posts a, the whole constituting a strong and rigidframe having open sides. The said parts are preferably made of metalbars, which are angular or L- shaped in cross-section, the corner-postsa being preferably made by uniting two anglebars 12 13 by rivets c, asshown in Fig. 3.

c 0 represent horizontal guides afiixed to adjacent corner-posts andadapted to support a series of horizontal trays d. There are two seriesof guides 0, one series at each end of the frame, said guides beingpreferably L- shaped metal bars riveted at their ends to thecorner-posts. The trays d are shallow metal pans of sheet metal,preferably steel, and are adapted to move upon the guides c and bepartially projected from either side of the frame, each tray beingprovided with handles 612 to enable it to be conveniently moved. Meansare provided for preventing the trays from being projected far enough tomove the center of gravity of the rack outside the base of the frame,the base in this instance including the space between the points wherethe wheels or casters a at the four corners of the frame bear upon thefloor. The said means, as here shown, comprise stop-ears d, affixed tothe trays 0Z and projecting outwardly from the ends ofthe trays over theguides c and between the corner-posts to which said guides are affixed,the arrangement being such that the stop-ears d abut against thecorner-posts, as indicated in Fig. 2, and thus limit the projection ofthe trays. As will be seen by reference to Fig. 1, the arrangement ofthe stop-ears is such that considerably less than half the width of anytray can be projected from the frame. Hence if all the trays areprojected in one direction there is no liability of interference withthe equilibrium of the rack. The stop-ears d are also so arranged thatthe inner edge of a tray when fully projected is about midway betweenthe opposite sides of the frame, so that when one tray is projected fromone side of the frame, and the tray above it is projected from theopposite side of the frame the upper tray is entirely removed from abovethe lower tray, and the latter is therefore exposed, so that it can beconveniently loaded and unloaded.

The described rack is particularly useful for pie bakers, because itenables a large number of unbaked pics to be stored in one rack, movedto the oven; and conveniently transferred to the oven. After the pieshave been baked they are returned to the rack, which may be then wheeledto the point from which the pies are to be taken for delivery.

I claim 1. A rack of the character stated comprising a portable framehaving vertical cornerposts, and horizontal guides attached to theposts, and horizontal trays movable on said guides and adapted to bepartially projected from either side of the frame, the trays and framehaving complemental stop members adapted to limit the projection of thetrays and prevent the center of gravity of the rack from being movedoutside the base of the frame, the arrangement being such that theprojection of two adjacent trays in opposite 20 directions exposes thelower tray.

2. A rack of the character stated comprising a portable frame havingvertical cornerposts, and horizontal guides attached to the posts,horizontal trays movable on said guides and adapted to be partiallyprojected from either side of the frame, and stop-ears affixed to theends of the trays and projecting between adjacent corner-posts andadapted to abut against said posts to limit the projection of the traysfrom the frame in each direction, the said ears being arranged toprevent the center of gravity of the rack from being moved outside thebase of the frame, and to cause a tray projected in one direction to beuncovered by the projection of an adjacent tray in the oppositedirection.

In testimony whereof I have afiixed my signature in presence of twoWitnesses.
